Are we planning to do something for Halloween?I thought that we could organize a pumpkin-lapm making workshop on Saturday (30th) and then we could use the rest of the pumpkin in the kitchen (pumpkin soup, cake whatever). In this way we would have both the decoration and the food for the next day. On Sunday we could make an exclusive free shop: use the stuff from the free shop for preparing costumes for the party.

It could be done. Mould wine takes a while to make, so people could bring a bottle and get a bottle's worth of mould wine back. It just wouldn't be the same one. You could have a couple of pans with a couple of bottles on the go (so that you don't end up with 10 different wines mixed together), and a funnel and strainer.
